Description

Lighting device and LED module thereof

technical field

The present invention relates to a light source module, and in particular to a light emitting diode (LightEmitting Diode, LED) module.

Background technique

A light-emitting diode is a semiconductor element, which is mainly composed of III-V group element compound semiconductor materials. This semiconductor material has the property of converting electrical energy into light. In detail, when an electric current is applied to this semiconductor material, electrons inside the semiconductor material will combine with holes, and the excess energy will be released in the form of light, thereby achieving the effect of luminescence.

The luminescence phenomenon of light-emitting diodes is generally considered not to be thermal luminescence or discharge luminescence, but to be cold luminescence, so the life of the light-emitting diode device can be as long as more than 100,000 hours, and there is no need for warm-up time (Idling Time). In addition, light-emitting diode devices have the advantages of fast response (about 10-9 seconds), small size, low power consumption, low pollution (mercury-free), high reliability, and suitable for mass production, so their application fields are very wide .

Because light-emitting diodes have a longer service life and lower power consumption characteristics, light-emitting diodes have gradually replaced fluorescent lamps and incandescent bulbs in some fields, and their applications are becoming more common, such as scanner lights that require high-speed response Source, backlight or front light of liquid crystal display device, instrument panel lighting, traffic signal lights, large-scale display electronic billboards, and general lighting devices.

Generally, most of the existing light-emitting diode modules are arranged in a linear arrangement, and usually the linear arrangement of the light-emitting diode modules is suitable for application in long strip lamps. If the linearly arranged LED modules are applied to circular or other shaped lamps, many blank areas will be left, which will affect the overall appearance of the lamps. In addition, because the existing LED modules are used in lamps, when one of the components of the LED module fails and needs to be repaired or replaced, the entire housing of the lamp must be disassembled together, which will increase the difficulty of maintenance and maintenance. cost.
